Hi Guys,

What Unix Versions do Production servers usually use?

Sun Solaris, HP-UX, IBM AIX, FreeBSD and Apple Mac OSX are all Unixes.
You can check the latest version for each one of them

...usually use?

All production servers use CentOs, for some value of 'all'.

Adding my voice of confusion to the mix.
  • The company I am currently at uses Ubuntu Linux
  • The previous company were > 99% Red Hat Linux
  • A company further back used AIX for their main Unix systems
  • A company further back used FTX for their main Unix system

  • With the exception of the current company, these were all large companies (>5000 employees each) with very significant web presence.

    Actually, most of the answers are about the distributions that are used, and not about the version of the distribution.

    Perhaps the OP can respond with more on what you are looking for, and why?
    As posted, its not a very useful question, so its hard to give a good response.
